I can determine a hyperbola in this equations, like finding the foci, axes, vertecis, intercepts?
x^2+y2=100 <--- is a circle
xy=48
how can i write this $\displaystyle y= \frac{48}{x}$ into this equation $\displaystyle \frac{x^2}{a^2}-\frac{y^2}{b^2}=1 $ of hyperbola?
I graphed this y=48/x
it turns like this:

but i dont know how to get the foci, axes, vertices, etc.
please help thanks!
